Earlier quoted context omitted.

The most likely explanation is that the chase never actually happened, and the police are making it up. We should be long past the point of uncritically believing everything police claim.

There were two helicopters involved, border patrol and tucson police. They also phoned into the FAA as it was going down. They also made visual contact with the light on the underside of the drone: "From what I can tell just from its position light, you know, I would have to imagine it was larger than a quadcopter"

maybe the 2 helicopters were chasing each other

Those are crewed, or occasionally towed behind a normal boat. It should be relatively straightforward at this point to build a sub that can navigate entirely by itself.

GPS doesn’t work underwater. Almost all the drone tech navigates by GPS; converting over to an inertial nav system and making that reliable for autonomous underwater operation is a good bit more than “relatively straightforward” I think.

Narcosubs are typically just barely sub-surface, they don't operate deep like navy subs.

The portion above water is designed to be low enough to be hidden by waves but is still above the surface so using GPS wouldn't be an issue.

The biggest barriers are the law and liability. There is a lot of red tape, and rightfully so. Flying heavy items over residential areas comes with a lot of risk, risk that someone doing so illegally, with an untraceable aircraft, likely would not care about.

And you're 1.) competing against the economics of standard delivery vehicles 2.) Ref: law/liability. At scale you're possibly violating airspace of people's property and, while I don't expect people in non-rural areas to start using them for skeet practice in general, I would expect lots of complaints to the government if they become annoying.

> you're possibly violating airspace of people's property

There is no such thing in the United States. All airspace is under federal jurisdiction, and the only agency with rule making authority is the FAA.

With 70+ minutes of flight time, maybe it wasn't battery powered but rather powered with liquid fuel.

Confirmed by a tower? The tower's tracked it with radar. That's how they called out the height. There would be logs.

Easily done via small IMUs with aiding from GPS using a surface-tethered antenna.

Clearly people have some rights to the space over their property. Case law isn't well established but, outside of airport landing rights, the consensus seems to be something like 400 feet which is in general uncontrolled airspace.

I probably won't shoot down a delivery drone though I may file a complaint. But if a drone starts poking around at low altitude over my property, it will definitely be skeet shooting practice time (on a rural property).

Neither do most narco“subs”, which are mostly semi-submersible.

Somewhat off topic, what I find curious is that gangs have not yet started really making use of drones. I've heard of them being used to drop drugs and phones into prisons, but not much else. Some of the higher end hobby drones can fly just as high as general aviation aircraft and really fast and carry a lot of weight. Or perhaps I have missed the stories?

They do https://english.elpais.com/spain/2021-07-15/spanish-police-s... https://www.businessinsider.com/how-mexicos-cartels-are-usin... P.S. you can buy the drone in the first article for a few 1000’s $ on Alibaba…

I don't think there is anything that has a wingspan of 4.5 meters and a capacity to carry 150 kilos of cargo.

You have any links?
